Hey, I have been using iPhone SE for the past few months. It's a 4-inch compact phone with plenty of features. But now, I'm facing Wi-Fi connectivity issues after the recent software update. Wi-Fi is automatically turned off when the phone is locked or in the sleep mode. I hope Apple’s next iOS 11 update could fix at least some of these problems, but each and every iOS update comes with its own collection of issues. It's really disheartening. I'm planning to sell the old phone and buy a new phone as early as possible. I came to know regarding an online service for selling used iPhone SE in Canada. Can anyone help me with this? Please share your valuable suggestions as early as possible.
